Patented June 20, 1933 UNITED STATES PATENT OFFICEY BURTON S. FLORADAY, OF TOLEDO, OHIO, ASSIGNOR T THE DUR-A COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO ELECTRIC LIGHT Application led January 11, 1932. Serial No. 586,050.

This invention relates generally to lights and refers more particularly to lights of the self-contained portable unit type adapted to be supported in a holder upon a wall or other T- upright member.

One of the essential objects of the invention is to provide a light wherein a switch at the lower end of a battery casing is adapted to be operated by a part of the holder to l control the illumination of a bulb at the upf per end of the battery casing when the light is received within the holder.

Another object is to provide a light wherein the switch'referred to is operable autofi matically when the light is removed from the holder to close the circuit to the light bulb so that the bulb will be illuminated when the light is carried in the hand.

A further object is kto provide a lightwherein the switch may be operated manually after the light is removed from the holder so that the support to the light bulb will be opened and will remain open regardless of whether the light is carried by hand or is returned to the holder.

A further object is to provide a light wherein the cup thereof isprovided with a pivotal ring that is in an inoperative out of the way position about the reduced portion of the cup when the latter is within the holder but is capable of being swung outwardly to an operative supporting position after the cup aforesaid has been removed from the holder.

A further object is to provide a pivotal ring which is associated with the cup in such a way that it is capable of supporting the light in raised position in the holder above the stud 27 whereby the circuit to the bulb 'i9 may remain closed while the light is in the holder. Y

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, where- 1n:

Figure 1 is a front elevation of a light mounted in a holder on a wall; f

Figure 2 is a vertical sectional view through the structure illustrated in Figure 1;

Figure 3 is a fragmentary vertical sectional view of the holder and the light just before the light is received within the holder;

yFigure 4 is a fragmentary vertical sectional view of the light and showing the movable contact element held in inoperative electric light bulb 2 having its terminal 3 anchored within the upper end 4: of the casing, an electric battery 5 within the casing and preferably comprising two dry cells, and

an electric switch unit C at the lower end of the casing. Preferably this unit C includes a cup 6 threadedly engaging the lower end'of the casing 1 and having a reduced end portion 6', a ring 6 pivoted to the cup 6 and adapted to encircle the reduced portion 6 of the ring, a disc 7 o-f insulating material fixed i in the cup 6 in spaced relation to the bottom 8 thereof, a coil spring 9 on the disc 7 and holding the battery 5 against the bulb terminal 3, a strip 10 of sheet metal anchored on the disc, having tongues 11 holding the lower convolution 12 of the spring and having a prong 13 extending downwardly through the disc 7, and a spring metal strip 14 secured to the prong 13 on the underside of the dise 7 and having a free end 15 urged downwardly and provided with a depending lip portion 16 that is engageable with the bottom 8 of the cup to close the circuit to the bulb 2. Thus in this construction the strip 14 constitutes the movable electric contact element, while the bottom 8 of the cup constitutes the stationary element. Preferably the strip 1/1 is provided intermediate its ends with a depending transversely eXtending corrugation 17 and the bottom 8 of the cup is provided below said strip in vertical alignment therewith with a key hole slot 18. A suitable manually perable button 19 of insulating material is slidable in the narrow portion 20 of this slot and engageable with the corrugation 17 to raise the lip 1G from the bottom 8 of the cup and canse the circuit to the bulb 2 to be opened. Any suitable means such as the crimped edge portions 20 and 20 of the narrow portion 2O ot the slot may be utilized Jfor holding the button in said narrow portion 20 while in use. Preferably the construction of the button 19 is such that the lip 1G may bear against the bottom 8 of the cup and close the electric circuit to the bulb 2 when the button 19 is upon either side of the corrugation 17. It is only when the button 19 is directly below the corrugation 17 that the lip 16 is disengaged `from the bottom 8 of the cup and the circuit to the bulb 2 is open.

The holder B preferably comprises a bracket 2O having an upright strip portion 21 attachable to the wall 22 or other suitable i f support and having ay curved base portion 28, a shelf 2e fastened by a rivet to the curved base portion 23, a cup-shaped body 26 fastened by the rivet 25 to the shelf 24:, and a stud 27 ot insulating material rigid with the rivet 25 and projecting above the bottom 28 oiC the cup-shaped body 26.

ln use the button 19 may be moved longitudinally ot the slot 1S to one side or the other ol' the c rrugation 17 to permit the lip 16 5' to engage the bottom 8 of the cup and thereby close the circuit to the bulb 2, or may be moved under the corrugation 17 to cause the lip 16 to be raised from the cup bottom 8 so 'that the circuit to the bulb 2 will be opened. Should the light A with the button 19 at one side or the other ot the corrugation 17 be Iinserted into the cup-shaped body 26 ot the holder B, the stud 27 will be received in the slot 1S and will abut the corrugation 17 with the result that the lip 16 will be raised 'trom the cup bottom 8 and the circuit to the bulb 2 will be opened. When the light A is removed 'from the holde B the stud 27 will be disengaged from the corrugation 17, consequently the lip 16 vill engage the cup bottoni 8 and will again close the circuit to the bulb lifhile out of the holder the button 19 may be moved into engagement with the corrugation 17 to cause the lip 16 to Ybe disengaged from the cup bottom 8, and should the light then be returned to the holder B, the button 19 will abut the upper end of the stud 27 but will not be moved thereby, consequently the switch parts will remain in the o )en position in which they were before the light A v-fas placed in the holder B. However, when the .button 19 vis at one side or the other of the corrugation 17 and the ring 6 is inclined relative to the bottom S ot the cup C5 and the light is placed within the holder, as

illustrated in Figure 6, the corrugation 17 vill be spaced above the upper end of the stud 27, consequently the lip 16 will remain in contact with the bottom S ot the cup and the circuit to the bulb 2 will remain closed. Then the light A is removed from the holder the ring 6 may be utilized as a support for the light.
